Help: identify

Find changesets by keywords (author, files, the commit message), revision
number or hash, or revset expression.

hg identify [-nibtB] [-r REV] [SOURCE]

aliases: id

identify the working copy or specified revision

Print a summary identifying the repository state at REV using one or
two parent hash identifiers, followed by a "+" if the working
directory has uncommitted changes, the branch name (if not default),
a list of tags, and a list of bookmarks.

When REV is not given, print a summary of the current state of the
repository.

Specifying a path to a repository root or Mercurial bundle will
cause lookup to operate on that repository/bundle.
